<p>[Problem] To provide an extension tube winding unit and an oxygen concentration device that are: capable of preventing an extension tube from twisting or kinking and oxygen supply being stopped, when a patient is using the extension tube, connecting a nasal cannula or other cannula, and inhaling oxygen; and capable of reliably detecting fire in the extension tube when the cannula has ignited as a result of an accidental or other fire, and of ensuring safety during use. [Solution] An extension tube winding unit (800) comprising: a winding member (835) for winding an extension tube (801) connected between an oxygen concentration device (10) that generates concentrated oxygen and a cannula (22); and a detection unit (370) having a temperature sensor (320) that detects temperature increases in the extension tube (801).</p> |
